Pavel,
No offense, and no disrespect, but I think you picked the wrong forum. Unless your project involves Amateur Radio, I doubt there will be many here that will be able to help you. This is a rather specialized forum, and doesn't really deal with computer software in general, but mostly in the specialized area of Amateur Radio applications. There may be some experts that will reply, but it seems unlikely at this point.
I hope you have more luck on other forums, that are more specialized in the area you working, and I'm sure you will.
Good Luck.
